The ST5 was designed for those who cannot get grid electricity easily and economically. or those that realize the uncertainty of total oil dependence or total utlility dependence. The ST5 is a rugged design producing over 5 hp. Virtually any combustible material is a fuel. Wood pellets, husks, chaff, peanut shells, weeds hay, cotton waste, other agrobyproducts, natural gas. The engine uses a blower operated by the ST5 itself. Before the engine can be started, however the blower needs to be operated for 10 minutes either by a battery or by hand cranking.
First Optical Rectenna Converts Light to DC Current
The optical rectenna, you could think of it as like a radio antenna, only for the sun. It's working off of very similar principles, where we instead have very tiny antenna that match the size of the energy coming from the sun or visible light. And when that energy is coupled into the antenna, then another device is used to extract the energy and turn it into electricity. So making a rectenna is actually a pretty simple process, which was part of the beauty of the discovery. You basically take any type of conductive substrate,.
And we can grow these carbon nanotubes like a carpet vertical off the substrate. We grow our nanotube. We can formally coat them with something that is an electrical insulator, then we deposit another layer of metal on top to create a socalled metal insulator or metal diode structure. And so that diode structure is important, because it's the fastest diode in the world. And it's the only diode that's fast enough to open and close the gate at the speed of solar energy oscillating in an antenna. What gets me excited today is that we've done it.
Satellite dish solar cooker cooking sausage
Alright, today I'm going to do another test of my parabolic cooker. In my last tutorial that I did about this I mentioned that I needed to use a different method of mounting the pan. So today I'm using my camera tripod to do that and I think it's going to work out just fine Today I'm gonna cook some Italian sausage along with some peppers and onions so I'm gonna go ahead and put it on the tripod and see how long it takes one thing I was concerned about is how much sun this tripod would block but.
I see it's gonna work out pretty well There's a little bit blocked right here and also there's a shadow here cast by the leg and then a little shadow back here that comes from the pan The reason this works out pretty good is that these satellite dishes are not perfect parabolic shape. they actually. the satellite signal would normally come in from what is the top of the dish and bounce back toward the bottom of the dish where the receiver is at and so because of that I have this thing pointing straight up but sun is actually at a.
Slight angle so it can come in here between the legs of the tripod without getting blocked and then it can bounce up here to the pan which can be off center a little bit, so I think this is actually going to work out well for use with the tripod. Alright, the food has been in there about ten minutes and I see the lid of the pan is steamed up a little bit so I want to go ahead and open it up stir it around a little bit.
Illinois Solar Decathlon 2011 Tutorial Walkthrough
The University of Illinois' Rehome offers a new solution for disaster relief housing. This twomodule home is designed to be quickly transported and easily assembled in the event of a natural disaster. The Rehome also serves as more than a shelter it enables individual and community recovery through a socially and environmentally aware response. The two modules are prefabricated at a modular home manufacturer using standard 2x4 construction with spray foam insulation. Additional insulation is then added to the exterior of the walls using rigid foam panels. This tactic provides a highly insulated, airtight structure that cuts down on the amount of.
Energy needed to condition the home. Cedar siding is used as a rain screen to complete the exterior walls. There are two large deck spaces and a ramp constructed from reclaimed wood. The deck spaces extend the livable area of the home and encourage community and family interaction. Covering the deck are easily assembled shading canopies that define the area and shade the windows along the western and southern faade. A 7.2 kW photovoltaic system comprised of integrated photovoltaic and shading panels along The front faade and 24 adjustable modules on the roof, generates enough power to operate the Rehome. The panels can be shipped flat.
On the roof and adjusted to the correct angle on site. The landscaping surrounding the deck space provides privacy and edible vegetation that can easily be grown locally in the Midwest. The front door of the Rehome leads to a main living area of the house. Here, there is seating available for large groups, with two couches, eight slim folding chairs, and bar stools. The living room opens up to the kitchen containing highly efficient appliances, including an induction stovetop and a low flow faucet. The mechanical space hot water heater and HVAC system, is located in the main hallway.
The HVAC system is comprised of an airsource heat pump with energy recovery that is specifically designed for highly insulated, airtight homes. The bathroom of the Rehome is ADA compliant and utilizes low flow, water conserving fixtures. Water usage is monitored throughout the home and grey water is treated and used for irrigation. The master bedroom features cork flooring, and offers plenty of storage space in the hishers wardrobe, and under the bed. The master bedroom also has a private deck space. A flexible space in the living room can be adapted to each family's needs. For a couple.
New solar system for improved energyefficiency
Finding creative solutions to energy issues and energy efficient buildings has become a major priority for Europe in recent years. Today simple, nonpolluting technologies are deployed quickly. This industrial building in Malta hosts the prototype of an EUfunded optical system developed in the framework of the European project DiGeSPo. Its Concentratedsolar technology will be used to produce heat and electricity. The system uses mirrors with a tracking system to focus sunlight onto a receiver which contains a heat transfer fluid. The EU is aiming for a 20 cut in Europe's annual.
Energy consumption by 2020. Digespo is contributing to that objective by developing a new solar technology. The prospects of strong growth for Concentrated Solar Power over the next few decades seem good. This will help develop a competitive industry and foster EU partnerships. As we are all aware, there are about 160 million buildings within Europe. We see this as a unique challenge to be one of those buildings where we can generate energy efficiencies and energy improvements. Houses and buildings consume up to 40 of total EU energy use. Digespo and its mini solar power systems will.
In the long run allow homes and workplaces alike to generate their own electricity and meet their heating and cooling requirements. The Digespo project is a fantastic opportunity to exploit the huge potential and solar resources especially on an island like ours or in the Mediterranean region but also a very good opportunity for us to transfer knowledge which is mostly acquired from mainland Europe and solar research to the Mediterranean region in general. This is just the beginning As we become bigger consumers of energy, the European consortium of the DiGeSPo project wants.
Desert Solar Power for US Europe. Transmission over long distances. Energy keynote speaker
Generation, yes we can talk about wind turbines. We can talk about solar energy. You know, one of the most exciting things abouts the new technology coming is that we have the ability to take power up to 4 thousand kilometres from where it was made, to where it will be consumed. This is new. We can do it with almost zero power loss. Using technology from Siemens and other companies. This means that we can build solar generators in the Sahara Desert, to power Moscow, or Madrid, or the whole of Turkey. We will only need an area of the Sahara,.
200 kilometres by 40 kilometres in size, covered with mirrors, each mirror computercontrolled, shining its power onto a gas turbine. We only need that size to power the whole of Europe. So, we are in an extraordinary place. At the same time we're seeing, of course the acceleration of funds available to drive these things through carbon trading and in each of these, I see a parallel coming in water, which I'll come back to in a moment. Certainly, I do in the political sphere. We've seen tribalism in energy supply.
Appalachian States Solar Decathlon 2011 Engineering Audiovisual Presentation
Every square foot of land is designed and developed to live sustainably, to maximize resources. So instead of taking space to grow crops, now we're harvesting solar energy. Sure, we could have systems that were custom, well very expensive and custom jobs, but that's not really a homestead attitude. One of the new features of our Solar Homestead is a modern Trombe wall. We use the thermal leverage, if you will, of phase change materials they melt at a constant temperature so as long as you have phase change materials melting.
You don't overheat. We melt at about 27 to 29 degrees C Celsius. As the sun comes in you melt the phase change materials stays warm but not too warm, and we don't have to have as much thermal mass. The phase change materials leverage, because you're changing phases, you have lots of thermal mass available. As you get afternoon sun the wall will warm up, and when it cools down at night, and you need the heat, they will reradiate the heat back into the space. Our photovoltaic power system is incredibly dynamic. One aspect being.
The fact that we are a completely zeroenergy home, with an 8.2 kilowatt system. We are integrating bifacial solar panels. The panels that we decided to go with on our house can collect solar radiation from both sides. Obviously this is a nice performance boost. It did lead to some interesting design scenarios where you had to account for that extra boost, and prepare your system for higher than normal currents of voltages, but overall it's a perfect match. Another innovation in the Solar Homestead is the integration of two technologies, a.
Skylight, and solar thermal collection. So we call it the Solar Thermal Skylight. We decided to go with concentrators to cut cost basically, as well as reach the high temperatures, which is very critical for the latent energy storage the phase change material needs. We spent a lot of time picking out energy efficient appliances that are all Energy Star, of course. The rest of the team quickly pointed out that it also had to look good. We didn't want to be extravagant but we also weren't afraid to spend money, because it's important and.
That will pay back. Our house is very tight, it has controlled air infiltration and it also has a very robust thermal envelope where we reach R40 on all surfaces walls, ceilings, and floors. And we also have R5 windows. We don't need large HVAC systems. We decided to use the range hood as a whole house fan, so we could activate that if we needed to draw in fresh air into the house. We have separate passive fresh air openings, as well as some active ones. Most hot water heaters, as you've seen them, they're big tanks full.
Of water, and you have an element, an electrical element, for backup, and then you have a solar loop putting solar heat into it. We have no water, we don't store the energy in water, we store the energy in phase change materials. So we use a paraffin phase change material, and we pack the heat into that. And we can store nearly the same amount of heat as you can with a 200 gallon water tank. We're trying to build a reputation for the solar industry, in providing quality products at a good price that are going to work the.
